Cholesterol Hinders Lipid Nanoparticle Trafficking
2026-10-01
A 2025 study developed a streptavidin–biotin-DNA tracking and high-throughput imaging platform to resolve how lipid nanoparticle composition affects intracellular trafficking. Its findings identify cholesterol-driven accumulation in peripheral early endosomes as a pre-escape bottleneck that can reduce nucleic-acid delivery, while DSPC partially alleviates this phenotype.

PEG 400, Quercetin, and BCRP Efflux
2026-09-28
A 2026 International Journal of Pharmaceutics study integrated pharmacokinetics, spatial mass spectrometry imaging, transporter assays, and an inflammation model to explain how PEG 400 increases quercetin exposure. The findings indicate that solubility enhancement, altered UGT1A9-mediated metabolism, and reduced BCRP/MRP2 efflux jointly shape quercetin disposition and activity.

Glycine Preserves Ferritin and Iron Balance in Lens Cells
2026-09-24
The study links UVB-associated ferritin degradation in lens epithelial cells to disturbed iron homeostasis and cataract-related injury. It proposes that glycine acts through lysosomal PAT1, Nrf2, and PCBP2-associated iron handling to limit this disruption, offering a mechanistic basis for further cataract research rather than a demonstrated clinical treatment.
